I was able to pull the lifter out with a magnet examine it. It looked like it survived was able to put it back down in the hole. I removed some old rockers and pushrods off the spare 400 which I know nothing about. I have them side-by-side now the one with the tire wrap is in my 383 now with the bent pushrod. Although they look very similar on closer inspection the pushrod has a different dimple on outside (383 much larger dimple). Also the bottom of the rocker arm is also different in the center can I still use these? I can’t really tell where the pushrod sets in to the rocker if the recess is the same. I do see they don’t seem to have the same part number stamped on them. The one from the 400 engine is stamped I47 + The one from my 383 that I’m trying to fix it it’s kind of hard it’s some kind a triangle with the number in it so it appears. The pushrods from my spare 400 or the same length as my 383.
